How do I reach the best yield?

In order to achieve the best yield we must supply the elements in the proper quantity and timing. A soil analysis can help in order to prevent any deficiencies.

How to reach the best protein content?

The protein content is linked to Nitrogen. So it is important the plant has nitrogen available at stem elongation stage.

How to improve the profitability of the crop?

To improve profitability of crop it is important to use an efficient nutrition, avoiding to supply element in excess (a soil analysis can help) and elements available in right stages. For this purpose the use of CRF it is the main solution.

Is it useful to supply organic matter?

Yes, it could be useful in particular in low OM soil but you must include the elements in the fertilisation program calculation in order not to have excess of elements (in particular nitrogen).

It is possible not to supply potassium?

In some areas with high content of potassium in the soil it is possible to achieve high yield even without potassium fertilisation, considering also that wheat in in rotation and K is applied to other crops.

Polysulphate: Polyhalite Based Fertilizers

The natural, multi-nutrient mineral fertiliser Polysulphate is the foundation of our Polyhalite-based fertilisers. We produce Polysulphate from polyhalite, the 4-in-1 mineral containing sulfur, potassium, magnesium, and calcium. Polysulphate is mined, crushed, and screened ready for use, giving Polysulphate its naturally low carbon footprint.

Polysulphate for Crops

Polysulphate has a natural prolonged nutrient release and is approved for organic agriculture. Its low pH, low salt index, and very low chloride content make Polysulphate a highly versatile, crop and soil-safe mineral fertiliser.

Polysulphate can also be combined with other nutrients to create fertilisers capable of providing even more nutrients in a single, extended-availability granule.

Polysulphate’s Unique Production

Polysulphate is a mineral fertiliser created from the natural multi-nutrient mineral, polyhalite. We mine polyhalite ICL Boulby, our mine in North Yorkshire, UK. ICL Boulby is the world’s only polyhalite mine, 1,200m under the North Sea. The raw polyhalite is transported to the surface, where it is crushed and screened, ready for sale to growers.

The Polysulphate Range of Fertilisers

Polysulphate is available in different grades: fine powdered Polysulphate Standard; small granules in Polysulphate Mini; and regular granules as Polysulphate Granular. In addition, we use Polysulphate in our Polysulphate-based fertilisers, for example, our Polysulphate Premium, ICL PKPlus, ICL PotashpluS, and more.
